Although the early morbidity and mortality rates in fulminant myocarditis are high, the long-term prognosis after passing the acute danger phase is favorable. An 11-year follow-up study showed that the survival rate of fulminant myocarditis was significantly higher than that of common acute myocarditis (93%, 45%, respectively), and the long-term survival rate was almost indistinguishable from that of the general population [1]. Violent myocarditis, also known as acute severe viral myocarditis, is mostly caused by viral infections (e.g., coxsackie B virus, adenovirus, etc.), which produce direct damage and immune response to the myocardium. Patients usually present with a history of upper respiratory tract or intestinal viral infections (e.g., fever, malaise, cough, diarrhea, etc.) a few days before the onset of the disease, followed by the rapid onset of acute heart failure manifestations such as severe arrhythmias, dyspnea, sweating, etc., and may be accompanied by respiratory failure and liver and renal failure, or even sudden death, with an extremely high mortality rate in the early stages of the disease. Sudden onset of myocarditis violaceum is extremely rapid, so if patients have symptoms such as cold, chest tightness, chest pain, fatigue and other symptoms in the prodromal stage, they should go to the hospital to find out the cause and follow the doctor’s instructions.
